Question 1(multiple choice worth 1 points)(07.06 mc)a group of students must collect at least $150 to organize a science fair. they have already collected $30. which graph best represents all remaining amounts of money, in dollars, that thestudents should still collect to organize the science fair? -210 -180 -150 - 120 -90-60 -300306090 120 150 180 210-210 -180 -150 - 120 -90 -60 -30 0 30 60 90 120 150 180 210-210 -180-150 - 120 -90-60-300 30 60 90 120 150 180 210-210 -180 -150 - 120.90 -60 -30 0 30 60 90 120 150 180 210​

1.$11.78

2.3x-2

3. Number line graph with closed circle on 120 and shading to the right. 4.yes ,because the total will be $3.27

 5.x 0 2 4

and y 0 24 48

6.x= 14

7.x=4

8.4.2

9.y= 4x

10.y=12x

Step-by-step explanation:

1.Lacey has total money for spend=$36

cost of 1 pair of sunglasse=$14.89

cost of a hat=$9.33

spend money =$14.89+$9.33=$24.22

Lacey has remaining money for buying scarf=$36-$24.22=$11.78

2.

If kim's age = x years

given that sam's age is 2 years less than 3 times kim's age

therefore the expression best shows sam's age is

3. A group of students must collect at least $150 to organise a science fair.

they have already collected money=$30

now remaining money =$120

hence ,the graph is number line graph with closed circle on 120 closed circle and shading to the right  which represents all remaining amounts of money.

4.Cost of a sticker=$0.35

Cost of an eraser=$0.99

Cost of pencil=$0.59

cost of 2 stickers =2*0.35=$0.70

cost of 2 erasers=2*0.99=$1.98

total cost including 2 stickers ,2 erasers and one pencil=$3.27

hence minni can buy 2 stickers and 2 erasesrs.

5. y= 12x

put x=0 in given expression y=12x then we get y=0

now put x=2 in this expression then y=24

and now put x=3 in this expression  then we get y= 48.

6.x+7.5=21.5

x =21.5- 7.5=14

8.

x=24*1/6=4.

8.x+2=6.2

then x =6.2-4=4.2

hence answer is 4.2

9.A store sold copies of a magazine =60

cost of 60 copies of magazines =$240

hence , cost of magazines is four times the number of magazines .

therefore , the expression is y= ( if number of magazines x)

y=4x; (1,4),(2,8),(3,12)

10.y is 12 times x therefore the relation between x and y is
